Good points. I am of a similar mind. Yes, sometimes it’s nice to boost a post for visibility, as a minnow without much steem power. But I hope people are mindful to do that for posts that offer a genuine value to their audience.
And yeah speculation is risky! It is a fun game for some, but I prefer the long game and to invest in platforms that have missions I believe in (such as Steemit).
I'm okay with minnows getting a little boost, but others are just exploiting it for maximum quick profit. That deprives others.
